1/4 is one of the fractions
Sry I don’t know try Socratic
Are you asking a question? If you're asking if the statement you made is true, yes that is correct.
If Nate paints the wall in 4 hours, it means that he can paint 1/4 of the wall every hour.
Similarly, if Jill paints the wall in 7 hours, it means that he can paint 1/7 of the wall in one hour.
So, together, they paint the following fraction of the wall in one hour:
.
At this rate, they need 28/11 hours to paint the whole wall, in fact, after that amount of time they paint

i.e. the whole wall
It'd be a lot easier to help you if you'd share the answer graphs.
Just so that you know:
<span>f(x) = log(x + 3) + 1 can be graphed as follows:
</span>
1. Graph y = log x. This function's domain is x>0. It begins in Quadrant IV and ends in Quadrant I. It intercepts the x-axis at (1,0).
2. Now move the entire graph 1 unit to the left. This gives you the graph of y = log (x+1).
3. Now translate this entire graph up 3 units. This gives you the graph of <span>f(x) = log(x + 3) + 1.</span>
